Le Leouff et al. 1992 showed that Bradycneme is a junior synonym of
Elopteryx nopscai.  It is a dromaeosaurid.

Like Paronychodon, Euronychodon does not seem to be dromaeosaurid.  Some
have suggested that the "paronychodontids" are closer to troodontids than
to dromaeosaurs, and others (Currie et al. 1990) have suggested that these
are deformed teeth of other known theropod groups.

Many workers agree that Saurornitholestes might be Velociraptor

Olshevsky has corrected the trivial nomen to "ostrommaysorum", since Ostrom
and Mays are two people.

Le Loeuff et al. 1992 showed that the French dromaeosaur is Elopteryx
nopscai (=Bradycneme = Heptastereornis)

There is no evidence that Coelurus is a dromaeosaurid.  If anything, it
might be ancestral to the troodontid-ornithomimid-tyrannosaurid group
Arctometatarsalia.

Ornithomimus minutus is not a dromaeosaurid.  It may be a troodontid, and
in an upcoming paper I'm suggesting it's a..., oh, maybe I'll make you
wait...

Daptosaurus was the name Brown was going to use for the animal we now call
Deinonychus.  Brown never used it in a technical paper, and the name was
forgotten.
